Wow thanks for the 365chess.com site, certainly a good replacement for non chess.com members opening database on chess.com.
From what I see, you already have many softwares, stick to the ones you already have :)
The best software to get ??
Sort:
Whats the best software one should get to get a full workout for chess commerical or non-commercial or features from diffrent websites. So far I have Rybka for blunder check , 365chess.com to see where the Novelties or Technical ones took place, SCID for data base uses, Chessgym.net for quick attack&defense training chess.com's tactics trainer I use slightly lately I've been using other tactics puzzel websites for my tactical trainning, and Chessmaster 10th edition to play out winning games against some of the master personalities.
Things Im going to use:
Megabase for my main game refrence database.
ChessHero for positional trainning.
Fritz Cloud feature (nuff said)
Any other software I should add or feature I dont use but should from another website ?
